Abstract

See full text

Methods and systems to determine ghost operators from marine seismic data are described. Methods and systems extract statistical information about the free surface from N gathers of pressure and vertical velocity data obtained for N activates of a source. Ghost operators are calculated from the N gathers of pressure and vertical velocity data. The ghost operators may be used to characterize the actual source and receiver ghosts recorded in the seismic data, compute properties of the free surface, such a reflection coefficient and root mean square free surface height, and may be used to deghost pressure and vertical velocity data.
